hi im getting my nissan 300zx in two months time and i have been researching different ones im getting a 1991 twin turbo auto targa prob 2+2. i have seen examples were the engine has siezed and the explanation for this was given as the previous owner had put standard unleaded fuel in rather than premium.

 

anyone know if the zx's have to be ran only on premium like optimax or something?

 

anyone any idea of the repair costs for a seized engine?

Imports should be run on optimax or super unleaded. UK cars are mapped to run on 95 ron (normal unleaded)

cheers m8 anyone any idea how much it would cost to sort out a seized engine on one?

Depends what they mean by seized?

Running on the wrong fuel doesn't cause that kind of problem.

If it needs a rebuild you're looking at thousands.

I am sure there was a thread recently about that car, it was on ebay or something

sorry but whoever started that idea is talking b*llocks im no mechanic but an engine wont "seize" due to running normal unleaded. lower octane fuel may cause det or pinking which in turn may damage the engine, but that wouldnt seize it, starvation of oil is what seizes and engine. always better to run higher octane fuel, i maen it may be 5p more expensive but whats that 50p per ten quid! not exactly crippling money!

It was talked about and heres the thread, zed engines are strong when serviced correctly.

Yeah, as said above that's rubbish. Better to run on super or optimax but octane 95 isn't going to cause the engine to seize. Read the service manual. Ain't gonna happen.

aye thats were i seen it on ebay thought it was a bit unlikely fuel could do that when i was reading it.
